Most laws of physics tell us what must happen. Throw a ball in the air and it will come back down. But physicist Chiara Marletto, a Research Fellow at the University of Oxford, says that laws like this only tell us part of the story.
She believes that the rest lies in 'counterfactuals': things that could be.
In her new book, The Science of Can and Can’t (£20, Allen Lane), she explains how these counterfactual properties could solve many of science’s biggest outstanding problems.
